(54) CDMA remote station and method of transfering data


(57) A method of transferring data for one of a plurality of wireless remote stations of wireless telecommunication network, the one remote station (RS) comprising an RS-spread-spectrum transmitter and an RS-spread-spectrum receiver, the method comprising the steps of:
  • receiving from a base station a broadcast common-synchronization channel comprising a frame timing signal at the RS-spread-spectrum receiver of the one RS;
  • determining frame timing at the one RS from the received frame-timing signal;
  • transmitting to the base station an access-burst signal from the RS-spread-spectrum transmitter of the one RS, the access-burst signal comprising a plurality of segments, each comprising a predefined preamble and a pilot signal, transmitting the segments at step-wise sequentially increasing power levels, the access burst signal starting at the beginning of an access slot, as defined by the frame timing;
  • receiving from the base station an acknowledgment corresponding to the transmitted preamble at said RS-spread-spectrum receiver and ceasing transmission of the access burst signal in response thereto; and
  • transmitting a spread-spectrum signal comprising any of data and power control information from said RS-spread-spectrum transmitter, in response to the receipt of the acknowledgment.
